AI Article Synopsis
Article Abstract
The non-classical effects of 1,25(OH)(2)D(3) create possible therapeutic applications for immune modulation (e.g. auto-immune diseases and graft rejection), inhibition of cell proliferation (e.g. psoriasis, cancer) and induction of cell differentiation (e.g. cancer). The major drawback related to the use of 1,25(OH)(2)D(3) is its calcemic effect, which prevents the application of pharmacological concentrations. Several analogs are now available that show modest to good selectivity with regard to specific effects (e.g. anticancer or immune effects or bone anabolism versus hypercalcemia) when tested in appropriate in vivo models. The molecular basis for this selectivity is only partially understood and probably a variable mixture of mechanisms.

Solvent Mediated Interfacial Microenvironment Design for High-Performance Electrochemical CO Reduction to C Products.

Electrochemical CO reduction (CORR) in membrane electrode assembly (MEA) represents a viable strategy for converting CO into value-added multi-carbon (C) compounds. Therefore, the microstructure of the catalyst layer (CL) affects local gas transport, charge conduction, and proton supply at three-phase interfaces, which is significantly determined by the solvent environment. However, the microenvironment of the CLs and the mechanism of the solvent effect on C selectivity remains elusive.

Retinal artery occlusion (RAO) is a critical ophthalmic emergency with a high risk of significant visual impairment. While traditional treatment aims to promptly restore blood flow to the retina, recent research has investigated the potential benefits of anticoagulation therapy for managing this condition. This paper reviews current literature and clinical trials investigating the efficacy and safety of anticoagulant and antiplatelet therapies, such as systemic heparinization and direct oral anticoagulants and aspirin, in treating RAO.

The precise identification of various toxic gases is important to prevent health and environmental hazards using cost-effective, efficient, metal oxide-based chemiresistive sensing methods. This study explores the sensing properties of a chemiresistive sensor based on a ZnSnO-SnO microcomposite for detecting -butanol vapours. The microcomposite, enriched with oxygen vacancies, was thoroughly characterized, confirming its structure, crystallinity, morphology and elemental composition.

3-Fluoroneuraminosyl fluorides are invaluable probes for studying the catalytic mechanism of sialidases (neuraminidases), and as sialidase inhibitors. Significantly, when a C-3 equatorial fluorine is installed on a C-4 functionalised N-acylneuraminic acid (Neu)-based template, the compounds are potent and selective inhibitors of both influenza and parainfluenza sialidases, and of virus replication. Typically, the reported syntheses of 3-fluoroneuraminosyl fluorides involve either an enzymatic or a chemical synthesis that have uncontrolled stereoselectivity in the introduction of fluorine at C-3 of Neu and consequently yield a mixture of C-3 ax and C-3 eq fluoro derivatives.

This study investigated possible mechanisms underlying differences between heterophilic and homophilic cadherin adhesions that influence intercellular mechanics and multicellular organization. Results suggest that homophilic cadherin ligation selectively activates force-transduction, such that resulting signaling and mechano-transduction amplitudes are independent of cadherin binding affinities. Epithelial (E-) and neural (N-) cadherin cooperate with distinct growth factors to mechanically activate force-transduction cascades.
